Use the sample data and confidence level to construct the confidence interval estimate of the population proportion p. n equals

FrozenT [24]

Answer:

(0.2599,0.3401)

Step-by-step explanation:

We are given the following in the question:

Sample size, n = 500

x = 150

$\hat{p} = \dfrac{x}{n} = \dfrac{150}{500} = 0.3$

Confidence interval:

$\hat{p}\pm z_{stat}\sqrt{\dfrac{\hat{p}(1-\hat{p})}{n}}$

$z_{critical}\text{ at}~\alpha_{0.05} = \pm 1.96$

Putting the values, we get:

$0.3\pm 1.96\sqrt{\dfrac{0.3(1-0.3)}{500}} = 0.3 \pm 0.0401 =(0.2599,0.3401)$

The 95% confidence interval is (0.2599,0.3401).

Use rounding or compatible numbers to estimate the sum. 256+321

olganol [36]

256 being rounded would become 260 and 321 would become 320 so adding up the estimates the would be 580 (real answer is 577)
